What’s the median of 1,2,3,4,5,6,7,8,9 and 10

5.5

Step-by-step explanation:

The median is the number in the middle of a data set.

First, lets arrange the numbers from least to greatest:

1,2,3,4,5,6,7,8,9,10

Now, cross one number off each end of the data set until we reach the middle.

1,2,3,4,5,6,7,8,910

2,3,4,5,6,7,8,9

3,4,5,6,7,8

4,5,6,7

5,6

There isn’t one number in the middle, there is 2 numbers(5 and 6). Therefore, we need to average the numbers.

Add the numbers, then divide by 2. We divide by 2, because there are 2 numbers.

Add: 5+6=11

Divide by 2: 11/2=5.5

Therefore, the median is 5.5

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
